What Is the Sauna Bo Nix Is Using to Recover From His Broken Ankle?

The Photo That Revealed Bo Nix's Recovery Setup

SISU founder Pete Nelson posted a photo standing next to Bo Nix in Nix's home gym, calling him "one of one." The caption referenced Nix's response to a brutal end to his season: a broken ankle suffered in the divisional-round win over the Bills, in a year where he'd led the Broncos through some of the best clutch quarterback play in the league. Asked how he handled it mentally, Nix said simply, "I trust in God's plan for me."

Nelson's response: "Man, imagine getting knocked down that hard and that's your response. It fired me up."

The device behind Nix in that gym is SISU's Crew Cabin Sauna, the brand's flagship traditional sauna, and it's now part of how he's rebuilding.

What Is the SISU Crew Cabin Sauna?

The Crew Cabin is a six-person traditional cabin sauna built in Ohio through Finn American and Amish craftsmanship, made from Western Red Cedar. It runs as both a dry and wet sauna between 110°F and 200°F, with a WiFi-enabled heater and UKU remote for precise control. Heating times run 50 to 90 minutes depending on target temperature, and on the high benches, SISU recommends staying in the 175-195°F range for a real traditional sauna session.

It's built around the traditional Finnish sauna model: real heat, real sweat, sustained exposure.

Why Heat Exposure Matters for Recovery

Traditional sauna use at high heat has been linked in large-scale Finnish research to improved sleep quality, reduced anxiety, lower inflammation, and measurable VO2 max gains. For an athlete rebuilding from a serious injury, that combination matters twice over. Physically, consistent heat exposure supports circulation and recovery. Mentally, it forces stillness and discomfort in a routine that's otherwise built around instant relief.

Why Pete Nelson and SISU Are Different

SISU wasn't built by a wellness marketing team. Founder Pete Nelson is a former gym owner and personal trainer who's run 33 ultramarathons, including a 50K in Antarctica, and once ran 40 miles alongside his father four months after his dad relearned how to walk following a stroke. Nelson built SISU around a single idea: heat builds grit, the same way suffering through miles does.

That's the same philosophy Nix leaned on in his own comeback. "Pressure is a privilege" isn't just a caption line, it's the thread connecting an NFL quarterback rebuilding an ankle and a sauna founder who's spent a decade testing his own limits in Cleveland winters and Antarctic ultras.

The Bottom Line

Bo Nix is rebuilding from a broken ankle the same way he plays quarterback: composed, disciplined, and without excuses. SISU's Crew Cabin Sauna is part of that process, built on a philosophy of intentional discomfort that goes back to founder Pete Nelson's own ultrarunning career.
